    AC servo motor grounding problem

    Hi All, We are now building a two-wheel robot and have constructed a locomotion module by using two Panasonic 3-phase AC servo motors. Could anyone tell me the servo motors and its drivers should be grounded to the chassis or to be completely insulated? Your answer could be a big help to us. Thanks.
